users cannot get response from Telegram

[tienhung36]

I found that when the intent is judged as 'greet', users cannot get response from Telegram.
when the intent is judged as 'out_of_scope', users can get response from Telegram.

rasa_core log when can get response from telegram:
rasa.core.processor - Received user message 'About Pepe Corp' with intent '{'name': 'out_of_scope', 'confidence': 0.9581602811813354}' and entities '[]'
